Question

Python

Write the class SodaMachine that will represent a typical soda vending machine (product name, price). An instance of SodaMachine has access to three methods, purchase, deposit and restock that will describe its interaction with the user returning strings. Tip: use the string format method

Here is the base code=====

class SodaMachine:
'''
Creates instances of the class SodaMachine. Takes a string and an integer
'''
def __init__(self, product, price):
#-- start code here ---

#-- ends here ---

def purchase(self):
#-- start code here ---

#-- ends here ---

def deposit(self, amount):
#-- start code here ---

#-- ends here ---

def restock(self, amount):
#-- start code here ---

#-- ends here ---

Here are some example out puts=====

>>> m = SodaMachine('Coke', 10)

>>> m.purchase() 'Product out of stock'

>>> m.restock(2) 'Current soda stock: 2'

>>> m.purchase() 'Please deposit $10'

>>> m.deposit(7) 'Balance: $7'

>>> m.purchase() 'Please deposit $3'

>>> m.deposit(5) 'Balance: $12'

>>> m.purchase()

'Coke dispensed, take your $2'

>>> m.deposit(10) 'Balance: $10'

>>> m.purchase() 'Coke dispensed'

>>> m.deposit(15)

'Sorry, out of stock. Take your $15 back'

>>> x = SodaMachine('Dr. Pepper', 8)

>>> x.restock(1) 'Current soda stock: 1'

>>> x.deposit(8) 'Balance: $8'

>>> x.purchase()

'Dr. Pepper dispensed'
